The drive functions but writes data at extremely low speeds (often below 1 MB/s). This is a classic sign of NAND degradation: the controller is spending an increasing amount of time performing error correction, bad block management, and reallocation.
Since this is a specialized hardware component rather than a retail product, a "complete paper" usually refers to its technical datasheet or firmware repair documentation.
